From: Ingo Molnar mingo@kernel.org Date: Tue, 5 Dec 2017 14:14:47 +0100 Subject: drivers/misc/intel/pti: Rename the header file to free up the namespace

From: Ingo Molnar mingo@kernel.org

commit 1784f9144b143a1e8b19fe94083b040aa559182b upstream.

We'd like to use the 'PTI' acronym for 'Page Table Isolation' - free up the namespace by renaming the <linux/pti.h> driver header to <linux/intel-pti.h>.

(Also standardize the header guard name while at it.)
